Globe mavharuvhu uye mavharuvhu gedhi mavharuvhu maviri anoshandiswa zvakanyanya. Izvi zvinotevera sumo yakadzama yemusiyano pakati pemavharuvhu epasi uye mavharuvhu egedhi.
1. Mitemo yekushanda yakasiyana. Ivharuvhu imhando yedzinde inosimuka, uye vhiri reruoko rinotenderera nekusimuka nedzinde revharuvhu. Ivhavhavha yegedhi inotenderera ruoko, uye hunde yevharuvhu inosimuka. Chiyero chekuyerera chakasiyana. Ivhavha yegedhi inoda kuvhurwa kwakazara, asi vheji yepasi haidi. Ivhavhavha yegedhi haina inopinza uye yekubuda nzira inodiwa, uye vheji yepasirose yakatsanangura mapindiro uye maburi! Ivhavhavha yegedhi inotengeswa kunze kwenyika uye vharuvhu yeglobhu mavharuvhu anovharika uye ndiwo mavharuvhu maviri anonyanyozivikanwa.
2. Kubva pakuonekwa kwechitarisiko, gedhi regedhi rakapfupika uye rakareba kupfuura vheji yepasi rose, kunyanya inosimuka stem valve inoda nzvimbo yakakwirira yakakwirira. Iyo yekuvharisa pamusoro pevharuvhu yegedhi ine imwe yekuzvisunga chisimbiso, uye vheji yayo yepakati yakanyatso sangana nevhavha yechigaro chekuisa chisimbiso chepamusoro nepakati pekumanikidza kuwana kusimba uye kusadonha. Iyo yevhavha yepakati inotsvedza yewedge gedhi vharafu inowanzoita 3 ~ 6 madhigirii. Kana kuvhara kwekumanikidzwa kwakanyanyisa kana kutonhora kuchichinja zvakanyanya, iyo yevhavha yepakati iri nyore kubatika. Naizvozvo, tembiricha yepamusoro uye yakakwirira-kumanikidza wedge gedhi mavharuvhu atora matanho ekudzivirira iyo yevhavha musimboti kubva kunamira muchimiro. Kana vheji yegedhi yakavhurwa uye yakavharwa, iyo yevhavha yevhavha uye chigaro chevhavha chisimbiso chepamusoro chinogara chakabatana uye chichikwizana kune mumwe nemumwe, saka iyo yekuisa chisimbiso iri nyore kupfeka, kunyanya kana vharafu iri munzvimbo iri pedyo nekuvhara, mutsauko wekumanikidza pakati pemberi nekumashure kwevhavha core yakakura, uye kupfeka kwenzvimbo yekuisa chisimbiso kwakanyanya.
3. Kuenzaniswa nevhavhavha yeglobe inotengeswa kunze kwenyika, mukana mukuru wevhavha yegedhi ndeyokuti mvura inoyerera inopikisa iduku. Iyo inoyerera inopikisa coefficient yeyakajairika gedhi vharafu inenge 0.08 ~ 0.12, nepo kuramba coefficient yeyakajairwa globe valve inenge 3.5 ~ 4.5. Simba rekuvhura nekuvhara idiki, uye yepakati inogona kuyerera nemativi maviri. Izvo zvisingabatsiri chimiro chakaoma, hukuru hwehurefu, uye nyore kupfeka kwechisimbiso chepamusoro. Iyo yekuisa chisimbiso pamusoro pevharuvhu yeglobe inofanira kuvharwa nechisimba chekumanikidza kuti uwane chisimbiso. Pasi peiyo caliber imwechete, kushanda nesimba uye imwechete dhiraivha mudziyo, torque yekutyaira yevharuvhu ndeye 2.5 ~ 3.5 nguva yevhavha yegedhi. Iyi poindi inofanirwa kutariswa kana uchigadzirisa torque yekudzora mashandiro evhavha yemagetsi inotengeswa kunze kwenyika.
Chechina, nzvimbo dzekuisa chisimbiso dzevharuvhu yeglobe inongobatana chete kana yakavharwa zvachose. Iyo hama inotsvedza pakati peiyo yakamanikidzwa yakavharwa yevhavha core uye yekuisa chisimbiso pamusoro idiki kwazvo, saka kupfeka kwechisimbiso chepamusoro zvakare kudiki. Kupfeka kweglobe valve sealing surface kunonyanya kukonzerwa nekuvapo kwemarara pakati pepakati pevharuvhu uye nzvimbo yekuisa chisimbiso, kana nekumhanya-mhanya kwepakati nekuda kweiyo yakasununguka yekuvhara mamiriro. Paunenge uchiisa iyo globe valve, iyo yepakati inogona kupinda kubva pasi pevhavha core uye kubva kumusoro. Kubatsira kwepakati inopinda kubva pasi pevhavha yepakati ndeyekuti kurongedza hakusi pasi pekumanikidzwa kana valve yakavharwa, iyo inogona kuwedzera hupenyu hwebasa rekutakura uye kutsiva kurongedza apo pombi iri pamberi pevhavha iri pasi. pressure. Kuipa kwepakati inopinda kubva pasi pevhavha yepakati ndeyekuti torque yekufambisa yevhavha yakakura, inenge 1.05 ~ 1.08 nguva yekupinda kwepamusoro, simba re axial pazinde revhavha rakakura, uye tsinde yevhavha yakakura. nyore kukotama. Nechikonzero ichi, svikiro rinopinda kubva pasi rinowanzokodzera madiki-dhayamita mavharuvhu egirobhu, uye simba repakati rinoshanda papakati pevharuvhu kana vharuvhu yakavharwa inogumira kusapfuura 350Kg. Mavharuvhu egorobhu emagetsi anotengeswa anowanzo shandisa nzira yepakati kupinda kubva kumusoro. Izvo zvisingabatsiri zvepakati inopinda kubva kumusoro zvinongopesana nenzira yekupinda kubva pasi.
5. Kuenzaniswa nemavharuvhu emagedhi, zvakanakira mavharuvhu eglobhu chimiro chiri nyore, kuita kwakanaka kwekuisa chisimbiso, uye nyore kugadzira nekugadzirisa; izvo zvisingabatsiri ihombe yemvura inopikisa uye mauto makuru ekuvhura nekuvhara. Mavharuvhu egedhi nemavharuvhu eglobhu akavhurika zvakazara uye akavharwa zvakazara. Iwo anoshandiswa kucheka kana kubatanidza svikiro uye haana kukodzera kushandiswa sekupinza inodzora mavharuvhu. Kushandiswa kwemhando yeglobe mavharuvhu uye gedhi mavharuvhu anotemwa nehunhu hwawo. Mumatanho madiki, kana zviri nani kuvhara-kuvharwa chisimbiso kuchidikanwa, mavharuvhu eglobe anowanzoshandiswa; mumapaipi eutsi uye mapaipi emvura akakura-dhayamita, mavharuvhu emagedhi anoshandiswa nekuti kushomeka kwemvura kunodiwa kuve kudiki.
